A	name "de.iptivi.net" is subdomain, public suffix is ".net", top-level-domain is ".net", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .net-domains preloaded: 10583 (complete: 276475)
A	Good: All ip addresses are public addresses
A	Good: Minimal 2 ip addresses per domain name found: de.iptivi.net has 3 different ip addresses (authoritative).
	Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: de.iptivi.net has no ipv6 address.
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
A	Good: No cookie sent via http.
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
A	Good: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (6 urls)

A	Good: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain de.iptivi.net, 3 ip addresses.
	Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain de.iptivi.net, 3 ip addresses.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.de.iptivi.net
	2. Header-Checks
U			No https result with http status 2 or 4 (standard-check) found, no header checked.
	3. DNS- and NameServer - Checks
A	Info:: 7 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.

A	Good: Only one SOA.Primary Name Server found.: mira.ns.cloudflare.com.
A	Good: SOA.Primary Name Server included in the delegation set.: mira.ns.cloudflare.com.
A	Good: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: mira.ns.cloudflare.com, tanner.ns.cloudflare.com
A	Good: All Name Server Domain Names have a Public Suffix.
A	Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
A	Good: All Name Server ip addresses are public.
A	Good: Minimal 2 different name servers (public suffix and public ip address) found: 2 different Name Servers found

	Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: cloudflare.com
A	Good: Name servers with different Country locations found: 2 Name Servers, 4 Countries: CA, CR, GB, US
A	Info: Ipv4-Subnet-list: 6 Name Servers, 4 different subnets (first Byte): 108., 162., 172., 173., 4 different subnets (first two Bytes): 108.162., 162.159., 172.64., 173.245., 6 different subnets (first three Bytes): 108.162.192., 108.162.195., 162.159.44., 172.64.32., 172.64.35., 173.245.58.
A	Good: Name Server IPv4-addresses from different subnet found:

A	Good: Name Server IPv6 addresses from different subnets found.
A	Good: Nameserver supports TCP connections: 6 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 6 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 6 good Nameserver
A	Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 6 good Nameserver
	Nameserver doesn't pass all EDNS-Checks: mira.ns.cloudflare.com: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
A	Good: All SOA have the same Serial Number
	Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.
	4. Content- and Performance-critical Checks
A	Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
A	Info: No img element found, no alt attribute checked
A	Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
